fifth and sixth a little shorter, rather broad, both truncate behind, seventh 

 longer and narrower, its operculum narrow and oblique. 



Nearly allied to S. angulifer (3363), the antennal structure different, 

 as is the under-surface of the head, the intrahurneral impressions are 

 deeper and more than half the whole length of the elytra, and the hind 

 tibiae are simple. The head of 3363 when carefully examined is seen to 

 be materially different ; there is no sinuation between the smaller eyes 

 and the hind angles, which latter, moreover, are somewhat outwardly 

 curved behind so that the space between them and thorax is considerably 

 larger. In S. eminens (2724) the sixth ventral segment is nearly the 

 length of the fifth, but it is semicircularly emarginate and encloses the small 

 seventh, which has a broad operculum.

 also obtained from Mr. Hall's leaf-mould. 



EUPLECTINI. 



Euglyptus Broun. Man. N.Z. Coleopt., p. 1411. 

 4167. Euglyptus sublaevis sp. nov. 



Oblong, attenuate towards both extremities, slightly convex, nitid : 

 rufous, elytra paler and brighter, antennae and legs light chestnut-red ; 

 sparingly covered with short, decumbent, flavescent hairs. 



Head obliquely narrowed behind the large prominent eyes, more con- 

 tracted in front, its distinct punctation much concealed by the slender 

 pubescence, the tubercles almost contiguous in front, but separated behind 

 by a deep channel which becomes broader towards the eyes. Thorax 

 as broad as long, widest and obtusely subangulate before the middle, 

 obliquely and much more narrowed in front than behind ; the discal 

 furrow deep and broad, lateral foveae deep and extending from the base 

 to the frontal dilatation, there is no distinct ante-basal transverse impression, 

 its whole surface smooth. Elytra suboblong, about double the size of thorax, 

 gradually narrowed before the middle, but rather broader than it is at the 

 incurved base, they are apparently without punctation ; sutural striae 

 distinct, with a short basal carina outside each, the dorsal impression 

 moderately deep, rather broad near the base, obsolete behind, its external 

 carina more elevated and thicker at the shoulder than behind. Hind- 

 body a third shorter than elytra, as broad as they are at its base, without 

 visible punctures, the segments subequal, the basal two slightly trans- 

 versely impressed in front. Legs elongate and slender. 



Antennae equalling head and thorax in length, basal joint slightly longer 

 and stouter than the oblong-oval second, the next nearly as long but more 

 slender and distinctly narrowed towards its base, fourth and fifth shorter 

 and oviform, seventh slightly larger than the bead-like sixth or eighth ; 

 ninth abruptly enlarged, not quite as broad as the tenth, which is rather 

 closely attached to the large conical acuminate terminal one, these three 

 distinctly pubescent. 



Larger than E. elegans (2460), the head not broader than the thorax 

 and less abruptly contracted in front, the sides of the thorax more pro- 

 minent before the middle, and the punctation almost altogether absent.
